CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 661,002, dated October30, 1900. Application filed July 27, 1900. Serial No. 25,040. (Nomodel.)

To a, whom it may concern:

Be it known that I, CHARLES SOHLARED, a citizen of the UnitedStates,residingat Columbus, in the county of Franklin and State of Ohio,have invented certain new and useful improvements in Car- Couplings; andI do hereby declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates more particularly to the type of coupling knownas the Janney.

The object of the invention is to provide an improved locking andsetting device of simple and economical construction for the movablepart or knuckle of such a coupling, whereby the cars can be antomatically coupled and locked when coupled and unlocked andsimultaneously reset for coupling.

The invention consists, primarily, in a locking-pin having attachedthereto a pivoted lever with a cam e ge adapted to act on a tongue ofthe knuckle to throw the knuckle or movable jaw to open or uncoupledposition when the said locking-pin is lifted, said pivoted lever beingactuated by the contact of its inner edge with a surface in the cavityof the coupling-head or draw-bar. The knuckle-operating lever is alsomade with a tooth adapted to engage a seat or notch in the draw-bar tosupport the locking-pin in its elevated position.

In the accompanying drawings, showing an embodiment of my invention,Figure 1 is a vertical sectional view taken on the line a: 00 of Fig. 2.Fig. 2 is a horizontal sectional view taken on the line y y, Fig. 1.Fig. 3 is a top or edge view of the removed knuckle on a smaller scale.Fig. 4 is a View looking to the right of Fig. 3. Fig. 5 is a verticalsectional View of the knuckle setting and locking pin. Fig. 6 is a viewof such device looking to the right, Fig. 5.

In the several views, 1 designates the stationary part of the draw-head,which is recessed horizontally, as indicated at 1*. This stationary partis also made with a vertical opening for the reception of thelocking-pin. In the horizontal recess is hinged at 3 the knuckle ormovable part of the coupling-head 2, havingatongue 2 formed asapartthereof.

The locking-pin comprises a frame 4, having a downwardly-extending leg 4at its innerside and a shorter downwardly-extending flange or projection4", that has its inner side inclined, as shown. Pivoted in the rear sideof the locking-pin is a lever 5, having at its forward side a cam edge5, adapted when the pin is lifted to act'on the tongue 2*, and at itsrear side a cam edge 5*, adapted by contact with a surface or wall 1 inthe drawhead to force the said lever outward, and therefore the tongue 2of the knuckle in the same direction. The lever 5 is made with a toothor point 5 at its lower extremity to engage a seat or notch 1 in thestationary .portion of the draw-head when the lockingpin has been liftedto the uncoupling position. This engagement of the lever with the notch1 sets the pin in the uncoupled position and holds or supports it thereuntil acted on by an approaching coupler.

The frame of the locking-pin is furnished at its upper end with slottedwalls 4,and sup ported hingedly in a link 6, passed through the slots ofthese walls, is a curved pin 7, the lower end of which works through anopening 4 in the frame 4. When the couplingpin is down, the end of thiscurved pin 7 protrudes by gravity through the opening 4 and under theupper wall of the horizontal cavity of the draw-head, and thus serves asa latch to prevent the locking-pin from jolting out of its place. Thelink 6 can beconnected to one end of aleverextending to the side of thecar, so as to be within reach of the trainmen without the necessity ofgoing be tween the cars; but I do not show this lever in my drawings,nor do I make any claim of novelty to such lever, because it is wellunderstood and is common to many forms of coupling.

The upper end of the knuckle-operating lever 5 is formed with a handle5, that can be employed to lift the locking-pin if the link 6 should bedamaged so as not to afford suitable place whereby it may be grasped.Ordinarily the locking-pin is lifted by means of the link 6, and thefirst lifting movement withdraws the latching-pin 7 ,so that thecoupling-pin can be further raised to cause the le ver 5 to act on thetongue 4. When the coupling-pin has been lifted to its full extent thatis, the extent permitted by a cross-pin 4 in the leg 4-the tongue 2 ispushed outward until the lower edge of the lockingflange 4t rests on theupperside of said tongue. In this position the cars can be separated,and the parts are set in position for recoupling. The coming together oftwo couplings the shop for repairs.

What I claim, and desire to secure by Letters Patent, is

1. In a car-coupling, a knuckle having a tongue thereon, a pin having atongue-locking flange or projection on one side and a ton rue-operating,lever on the opposite side, combined with a latch attached to thepinlifting device for automatically latching the aforesaid pin in itstongue-locking position, substantially as described.

2. In a car-coupling, the combination of a knuckle havinga tongue, amovable lockingpin therefor, and a lever pivoted to the locking-pinhaving a cam edge to operate the tongue, and a cam edge to contact withthe draw-head when lifted to move said lever against thetongue,substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES SGHLARED.
